Major League Baseball games are official after 5 innings of play, or 4.5 innings if the home team is leading. If a game is subsequently called or suspended, the winner is determined by the score after the last full inning unless the home team ties the score or takes the lead in the bottom half of the inning. Then the winner will be determined by the score at the time the game is called. When wagering on total runs or run lines, the game must go the regulation 9 innings, or 8.5 innings if the home team is leading, otherwise it will constitute a "No Action" wager, and all money will be credited accordingly.
